Hello Ercoupe Group. This is my first post since joining your group. I own a very nice full IFR tomahawk. I've had it for 6 years & like it a lot. I fly for business & file IFR on all trips.
I am now looking at a Ercoupe 415-C. I have researched this AC & like what I read. I have learned that this plane can be a risky venture if you don't learn all you can about its' history. The one item that is holding me back is that the engine has not run for 2 yrs. I has an autogas STC & the tanks are full of hi-test autogas. The tanks are also coated with a brownish stinky slime. This appears to be a varnish-like substance. The engine turns over very hard. This does not fell like rust, but more lile the piston & rings are glued to the cylinder walls by this same varnish-like glop. Have any of you faced this same problem & what can be done to clean the engine & the tanks/fuel system? If a solution is available, I will probably buy this plane & join your ranks. Thanks, John P. Parker
